Hvordan skal plastproduktet virke som en boble?? Vores ingeniørs svar er, at årsagen kan være i udstyret, plastskimmel, og kan også være i injektionsprocessen, følgende er årsagsanalysen af processen, håber at hjælpe dig med at løse problemet.
- Modtrykket ved skrueforstøbning er for lavt, og rotationshastigheden er for høj, hvilket får skruen til at vende for hurtigt tilbage, and the air is easily pushed to the front end of the cylinder with the material.
- Use multi-stage injection to reduce silver streak: fill the runner at medium speed — fill the gate at slow speed — fill the mold at fast speed — fill the mold at low pressure and slow speed, so that the gas in the mold can be eliminated in each stage in time.
- Insufficient material, too large feeding cushion, too low material temperature or too low mold temperature will affect the flow of molten material and molding pressure, resulting in bubbles.
- The injection speed is too fast, so that the molten plastic is decomposed by large shear action, producing decomposition gas; The injection speed is too slow to fill the cavity in time, resulting in the product surface density is not enough to produce silver streak.
- The injection pressure is small and the pressure holding time is short, so that the molten material and the cavity surface are not closely attached.
- Too high material temperature, resulting in decomposition. Barrel temperature is too high or heating imbalance, should gradually reduce the barrel temperature. The temperature of feeding section is too high, so that part of plastic premature melting is full of spiral groove, air cannot be discharged from the feeding mouth.
In addition to the above 6 injection molding process reasons, about the plastic mold and equipment factors, but these two aspects uncontrollable reasons are many. Welcome to discuss more with Jasonmould.
